The principles are the same across Linux distributions, but some
distributions share common configuration approaches. The examples
in these classes will generally reference both the Debian and the
Red Hat approaches.

Most of the above topics require a sequence of two or more classes for
completion. Such class sequences are progressive, and success requires
attendance for all classes in the sequence.

Each topic stands alone; there are no dependencies among them. The
assumption is that attendees are at least familiar with command-line
shells.

Because command-line skills are generally required, the command-line
essentials class (a one-class introduction) will be repeated.
